We report a rare case of a primary renal neuroendocrine tumor. The patient was a 64-year-old woman. The patient's chief complaint was gross hematuria. Dynamic contrast-enhanced computed tomography (CT) revealed a hypovascular mass 13 cm in diameter in the right kidney. The border of the mass was clear. A grossly contrast-impaired area and internal granular calcification were observed. A right radical nephrectomy was performed. Macroscopically, the mass was hemorrhaged and necrotic. It was diagnosed as a neuroendocrine tumor (NET) (Grade 2) histologically. Findings, such as hypovascularity, calcification, and necrosis, in our case were similar to those in previous reports. These findings are considered relatively characteristic of primary renal NETs.
